All that Glitters is one of the very first eyeshadow that i bought and probably have made the most use of. Although UD Sin is also a champagne shimmer, the gold pearl in this works very well for most of my eyeshadow looks.
I wear this color almost every single day. I love it WAAAY more than Naked Lunch, which I've never worn since I bought it and tried it on once. I found that Naked Lunch was chalky and not pigmented at all. All That Glitters is a beautiful champagne/gold color that looks wonderful applied all over the lid. It is buttery and smooth, easy to apply and blendable, and highly pigmented, basically everything that Naked Lunch is not.
I put off buying All That Glitters for the longest time figuring that it was too orange/warm toned for me (WRONG!) and that since I also had Naked Lunch, I didn't also need ATG (WRONG again!). This is very much like Naked Lunch but deeper in tone and makes a bit more of an impact.
